wrrN asses i EDWIN METHOD '0F MAKING PRoDUcnn To all 'whom it may concern: I

i l Fig 3 is a detail mg mechanism.

My invention relates to the making of producer gas and articularly relates to the manufacture of el gas used'in heatingvand for similar purposes. In existing 'methods i of malng such gas from solid fuel, great dificulty has been had in preventing clinkering and caking of the fuel bed and in avoiding^ the formation of v large holes or passages through the'fuel bed permitting the undisturbed passage of theair through the producer and'resulting in the uneven gasifying of the fuel and making of a leanv gashaving poor heating qualities.

The object of the invention is to provide a simple and effective process .in which 4the above difficulties are avoided and are' overcome and a rich gas having `gh heating value is easily and cheaply made.

The invention consists in maintaining a body of incandescent fuel in the producer and in regulating the fuel supply so as to spread the fresh fuel evenly over the top of and may be The invention/further consists -in preventing the caking of the fuel and in avoldingthe formation of channels or large openings through-the fuel bed and in regulatmgthe supply of air soas to gasify the fuel evenly over the surface lof the bed and form a rich gas having a practically uniform heating value.

In the drawings, 2 represents the furnace chamber of the heating furnace, 8 the Hat roof thereof supported upon transverse Water pipes 4, and 5 is the producer chamber at. the end opposite to that at which the billet or other metal pieces are fed in; This profA ducer chamber may be of any desired shape provided with either straight or sloping side 'Walls` The chamber is free from any rate bars, supports or other projections wich would interfere with the deklpe'c-icationof Letters Patent.V Application led November 30, 1907.

amount of feed at any particular point in the Width of the feed shelf. The bar 10 is reciprocated by anysuitable c nnections, as by the bell crank 12 connected rods 13 with b `Athe eccentrics on the driven sliaft 14.

In order to introduce air, I preferably pro` vide a blast box 15 having an outlet throat or port 16 leading through the side Wall of the producer, or' preferably throgh its lower Compressed air for this Wind boX is leading to opposite ends of the blast box. The blast boX 1s divided into' six chambers by baiile Walls 19 therein and. the inlet `end of each of these chambers so formed is con trolled by valves 20. The blast box is prefde ending flange 21 Which enters the Water scalp to com el the air to enter and ascend through the c arge. 22 are poke holes extending through the front of the producer. In the operation of the producer, the coal is pushed sidewise into the arge and descends therein in the ordinary manner. There are, however, nol grates or inside projections which retard thecharge. This charge rests on the'ash bed and descends -as the ashes are raked out through the Water seal. By pushing the charge in sideWise below the point of su ply, the fuel Ais s read 'evenly over the `be and there are no oles burned through thetop for easypassage ofthe air. The action in any portion may be varied by varying the draft 1n this portion and also by varyinlg the stroke of the pxusher in this portion. n practice, the pus ers are preferablyjreciprocated continuously andserve to continuously `force fresh fuel over the fuel bed, thus givmg auniform quality of gas.

The shapel and form of the producer may bevaried Widely. It may be connected by pipesto` the polnt of use instead of directly connected as shown. The air blast 'box may or interfere with the free descent of f burning the coa in said producer,-' ausing the coal to gradually descend byro'moying ashes from the bottom ofthe producer, continuously feeding ortigns fresh coal across the topogt e ,co supplying air under pressur e bottom of t e fuel bed and regulatin e rate of feedJfor the co'a ,andv air across. thewidth of the coal bed; substantially asjdescribed.
